Description

Dual Monostable Multivibrator TC74VHC123AF/AFK: Retriggerable TC74VHC221AF/AFK: Non-Retriggerable 2. General The TC74VHC123A/221A are high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS technology.There are two trigger inputs, A input (negative edge), and B input (positive edge).These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs.This device may also be triggered by using CLR input (positive edge).After

Features

(Note) (1) High speed: Propagation delay time = 8.1 ns (typ. ) at VCC = 5.0 V (2) Low power dissipation: Standby state: 4.0 µA (max) at Ta = 25  Active state: 750 µA (max) at Ta = 25  (3) High noise immunity: VNIH = VNIL = 28 % VCC (min) (4) Power-down protection is provided on all inputs. (5) Balanced propagation delays: tPLH ≈ tPHL (6) Wide operating voltage range: VCC(opr) = 2.0 to 5.5 V (7) Pin and function compatible with TC74HC123A,TC74HC221A type. Note: In the case of using only one circ.
